A writer in All the Year Itoimii gives a collection of instances where premature burial had oeiy nearly taken place, and also instances of resuscitation where death had been previously supposed to have taken place, and argues therefrom i the great probability that such interments are more frequent than is generally supposed. Most of the tacts are extracted from a debate upon a petition presented to the French legislature in 1860, and in which Cardinal Donnet, Archbishop of Bordeaux, took a leading part. The Cardinal stated no less than three instances which had occurred in his experience, where people were at the last moment rescued from being buried before death, although the appearances seemed to warrant the conclusion that they were dead. The petition alluded to set forth the danger of hasty interments, and suggested the measures thought requisite to avoid terrible consequences. Amongst other tilings, it was asked that the space of twenty-four hours between the decease and the interment, now prescribed by the law should be extended to eight-and-forty hours. The article from which we have quoted gives some remarkable cases of suspension of life in cases of drowning, which ought to be generally known, as showing that efforts to restore vital action ought not to be too hastily given over. "On the loth of July, 1829, about two o'clock in the afternoon, near the Pont des Arts, Paris, a body, which appeared lifeless, was taken out of the river. It was that of a young man, twenty years of age, dark complexioned, and strongly built. The corpse was discolored and cold ; the face and lips were swollen and tinged with blue; a thick and yellowish froth exuded from the mouth ; the eyes were open, fixed, and i motionless ; the limbs limp and drooping. 2{o pulsation of tin', hetrt or tnvc, of rcxpiratvw win prceptiblc. The body had remained under water for a considerable time; the search after it, made in Dr. Bourgeois* presence, lasted fully twenty minutes. That gentleman did not hesitate to incur the derision of the lookers-on, by proceeding to attempt the resurrection of what in their eyes was a mere lump of clay. Nevertheless, several hours afterwards, the supposed corpse was restored to liie, thanks to the obstinate xerseverance of the doctor, who, although strong and enjoying robust health, was several times on the point of losing courage, and abandoning the patient in despair." It is also shown that in suffocation by foul air andmephitic gas, suspended animation may be mistaken for real death, and a case is stated where a person thus suffocated with charcoal fumes and apparently dead, was restored to life only after dnvn lutura' unremitting exertions. A singular fact is mentioned in regard to persons who have died of cholera: " While M. Trachez (who had been sent to Poland to study the cholera) vws opening a subject in the dead-house of the Bagatelle Hospital in Warsaw, he saw another body (that of a woman of fifty, w ho liad died in two days, having her eyes still lirijzM, her joints supple, but the whole surface extremely cold), which visibly moved its left foot ten or twelve times in the course of an hour. Afterwards the right foot participated in the same movement, but very feebly. M. Trachez sent for Mr. Searle, an English surgeon, to direct his attention to the phenomenon. Mr. Searlo had often remarked it. The woman, nevertheless, was left in the dissecting-room, and thence taken to the cemetery. Several other medical men stated that they had made similar observations. From which M. Trachez draws the inference: ' It is allowable to think that many cholera pati"nts have been buried alive." Exposure to cold is stated to be another cause of the suspension of vitality liable to bo mistaken for actual death. "M. de, Parville now professes to place in any one's hands a seU'-acting apparatus, which would declare, not only whether tin1 death be real,but inmld leave in the hands of'the i.rperiment-n- a written proof of the reality of tlu: death. The scheme is this: It is well known that atrophine—the active principle of belladonna—possesses the property of considerably dilating the pupil of the eye. Oculists constantly make use of it, when they want to perform an operation, or to examine the interior of the eye. Now, M. le Docteur Bouchut has shown thii* atrophine has no action on the pupil when death is real. Til a state of b'thargy, the pupil, under the influence of a few c!r"js of atrophine, dilates in the course of a few minutes; the dilation also takes place a few instants after death ; but it ceases absolutely in a quarter of an hour, or half an hour at the very longest: consequently, the enlargement of the pupil is a certain sign that death is only apparent. " This premised, imagine a little camera-obscura, scarcely so big as an opora-glass, containing a slip of photograpic pa-TKT, which is kept unrolling for five-and-twenty or thirty minutes by means of clock-work. This apparatus, placed a short distance in front of a dead person's eye, will depict on the paper tlu1 pupil of the eye, which will have been previously moistened with a few drops of atrophine. It is evident that, as the paper slides before the eye of the corpse, if the pupil dilate, its photograpic image will be, dilated; if on the contrary, it remains unchanged, the image will retain its original i?i/,"j. An inspection of the paper then enables the experimenter to read upon it whether the death is real or apparent only. This sort of declaration can be handed to the civil officer,who will give a permit to bury, in return." It may be that in Franc, where people are required to bury their dead so early nl'ti r decease, tin- dangir of premature burial IF not cxatrfrrrai, . ml in ihi;- iiiiiitiy wlp"i'' under ordinary cii-cnmstatvi ?', Hie luxlii-, of tin dead are l.ept until ilerompofiitioii siets in, we do nol believe Hie danger of burying alive is one in twenty millions. A good deal ot excitement lias bei-n created in the public, mind by recent sensation articles in tKe daily papet'S, cxayferui/ntn' the Hyk of preinn- ture burial, and painting in high colors the value of an apparatus whereby a person so interred and returning to consciousness might by his own efforts extricate himself. We would be willing, however, to wager that however efficacious such an appaiatus might be, it would not, in this country, be practically tested once hi half a century. Electricity Applied to Manufacturing Textile Fabrics. ELECTRIC ENGRAVING MACHINE. A machine for engraving the cylinders of copper or brass employed in printing woven fabrics and paper hangings, is an invention of French origin. The voltaic current is used to determine, by means of -.'lectro-magnets, the slight simultaneous advance or withdrawal of any number of engraving diamond points from the varnished surface of the copper rol-1 lers to be engraved, according to the position of a correspond-' ing metal contact point on the non-conducting surface of a prepared pattern. The pattern and cylinder to be engraved are moved mechanically in concert, and the proportion - of, their relative movements can be varied by mechanical adjustment. The engraving points have a slight vibrating motion given to them, which scratches off the varnish whenever ! brought into contact with it, and produces a series of fine zigzag lines, which facilitate the retention of the pasty coloring matter used. The prepared pattern determines the moments at which this contact occurs ; and the concert between the movements of the pattern and the roller produces a similar agreement between the pattern and the figures engraved, which may clearly be made larger or smaller than the pattern in any desired proportion and in any required number. The copper when exposed is afterwards" etched by an acid bath. ELECTRIC LOOM. This extremely ingenious contrivance, in which the usual Jacquard cards are replaced by an electrical arrangement, worked by a pattern prepared in tinfoil with insulating varnish, is the invention of Cav. G. Bonelli, Turin. A simple metal plate, perforated with holes, each of which is provided with a kind of piston, successively plays the part of each successive paper card in the usual arrangement. The pistons fill up every hole that is not required, but are withdrawn by electro-motors from those holes which require at each beat of the. loom to be kept open. This is effected as follows : A sort of metal comb, each tooth of which is the terminal of a separate insulated conducting wire, rests on the prepared pattern. Whenever a tooth touches the tinfoil, a circuit is completed through its conducting wire ; but where a tooth rests on the varnish, the circuit is broken. Each conducting wire includes in its circuit an electro-magnet. The pistons already spoken of are each composed of a small soft-iron shank, and brass button-shaped head, and are all held horizontally in a frame, one opposite each electro-magnet. In one position of this frame, the heads of these pistons project through the openings of the metal card or perforated plate ; the diameter of each pole is a little larger than the head of the corresponding piston, each piston being exactly in the center of its corresponding pole. In this same position all the soft-iron shanks touch the poles of the corresponding magnets, and the metal comb rests on the prepared pattern. A certain number of the electro-magnets corresponding to the uncovered portions of the tinfoil, are, therefore active or attract the shanks, bat the others exert no attraction. The frame with the pistons is now pulled forward away from the magnets ; those pistons which are opposite the active magnets are held back, sliding in their frame, so that their button-heads pass behind the perforated plate ; but the other pistons come forward with the frame leaving the magnets. The perforated plate then drops a little way, and by this simple contrivance all those piston-heads that were in front of the plate are retained there, whatever pressure comes against them, for they are now eccentric from the poles. The plate in-this condition presents a perfect analogy with the common prepared card. A certain number of holes corresponding to the metallic part of the pattern are vacant, the rest of the holes are blocked up, and present an unbroken surface by which the proper hooks of the Jacquard loom are acted on during one stroke. The perforated plate is then brought back to the position first described, the prepared pattern is moved on a little step, and the same process repeated. When shuttles with several different colors are to be used, the pattern is subdivided into insulated portions corresponding to the separate colors by removing a very thin outline of foil round each ; all the parts correspouding to one color are afterwards connected. As each shuttle is thrown, the battery is brought in contact with the appropriate series of insulated patches of tinfoil, producing a succession of different cards, and the pattern is not shifted forward until all the colors are exhausted. After the completion of each fresh combination on the perforated plate, the battery circuit is broken by a proper contact-breaker, and the injurious spark is thus avoided, which would otherwise occur when the comb is lifted from the pattern prior to a shift.—The Student's Ta-t-Bool of Electricity. Durability of .Portland Cenicnt. It is somewhat difficult to ascertain the durability of modern substances, as manufacturers occupy themselves principally in producing cheaply, and pay little attention to experiments on durability. We, know very well that a modern coat doo. not last yo long as if it wen- made of clotli us inamuaci un d forty _vai'fl ago. yet wrs prcfel it liyjvawni ol its lineneSt-' of texture and tiie lovvness of its price. We can iweriain the quality of a pane of glass in regard to its clearness, transparency, polish, etc., but we raunot tell how long it will last before getting dull or ftwiiDtuig iridescent 'lolorij. It is not improbable that a good Portland cement may last for tens or even hundreds of years ; but we cannot prove this, as our experience and observations only embrace a period of fifty years. We do not know what other agents besides air and water may effect cement in the course of time, nor can we toll whether all cements are equally durable. This last idea forcibly occurred to me ten years ago, when a cement produced by a German house was used successfully in laying pipes at a distillery. Another cement procured in the following year from the same manufactory and used in the same puipose tell to pieces in a few weeks. This induced me to make, experiments, which I do not consider conclusive, but which may serve to prevent similar occurrences, and may also give the manufacturer a hint how to conduct experiments in this respect. These experiments served principally to determine the influence of warm and salt water, and of the air at different temperatures. In this manner I tried to concentrate the influence of time. My experiments were comparative ones, as they served for practical purposes, in order to determine which kind of cement should be used for a certain purpose. 1. I immersed set pieces of cement in water contain in g 15 per cent of common salt, in which I kept them for weeks at a temperature of 30 Centigrade. 2. The same pieces were then dried in the sun and again immersed in the solution. 3. I also made experiments with cement in tlie winter of 1850-57, by exposing it in a wet Ktate to the frost, and then immersing it in hot water, and nice versa. Some German cements stood these Superficial trials very well, others rather badly, and the English cement worst of all.—Reid't Translation of JApo'intz' Tr/atise. Our Importations from France. We gather from the report of Mr. Nieolay, dated April 29, 1809, that the importations of French goods during the period extending from July 1, 1863, to December 31, 18C8, were as follows: 1803 (six months)......................,; 54,2,'jy,403 I8i;4.................................." 82,':Uo,V3i ly!.................................. l:U4l',oG!l 1806.................................. 180,(17,8;!7 1807.................................. 14!l,994,25fl 1808.................................. 131,-157,3-ri Total...........................737,8;9,i-21 These importations were chiefly articles of luxury. Tin-New York Times in commenting upon this subject, remarks: "The articles of actual utility are fractional in value compared with those which enter exclusively into ladies' use. Thus, taking the year 18(30 as a basis of illustration, the reported value of merinoes, bombasines and crape was not less than $39,222,500 ; silks absorbed $0,790,193 ; shawls, $3,832,-50'5; kid gloves, $7,04(5,800; flowers and artificial feathers, $3,549,035 ; fancy goods, $8,005 037; buttons and trimmings, $8,701,273; laces, $2,478,020; jewelry and precious stones, $7,321,023 ; miscellaneous dry goods, $10,548,270. Here are, ten articles which in one year represent, in the cost prices at Paris, an aggregate of $104,104,202 ; and this sum was at least doubled when the consumers paid their accounts. And in this recapitulation we take no notice of the Paris boots and shoes, the hair, and the minor et cetera of which the ladies are the sole buyers. Nor does any statement founded upon certified invoices indicate the full extent to which the Paris trade is indebted to American buyers. To render this view complete, we must add the sums expended by American visitors, who are supposed to make their purchases without tin-slightest reference to cost." Refining Vegetable Oils. Mr. C. Michaud, of Honfleur, has discovered a new method of refining oil which will probably eclipse all those in general use at the present day. This method has just been communicated by M. Chevallier to the Societe d'Encourage-ment. While sulphuric acid is introduced into the oil in minute numerous streamlets, air is blown into the oi! so as to produce a great commotion in the liquid and to fill it with air bubbles. TV- mucilacv contained in the crude oil, being acted on by the acid, soon fnrm with the. air a, voluminous layer of scum at the surface, which is skimmed off as it iorms. This insufflation of air is repeated several times In succession, and the scums cleared off every time until the oil is clarified. At this point of the operation it still retains free, sulphuric, acid. It is now run into a eopjjer vessel, and steam is forced through it until the oil has reached a temperature ot 100 C. The steam is then allowed to bubble through for half an liour or an hour longer. After the oil has cooled down Some 20 or 30" ('., which may be done artificially, it is run through an ordinary filter. Two large refineries have lately been put up on the ' Michaud" plan, and the oil produced by them is so pure, that the wick of a lamp burning it will not caibonize after mauy days' usage. A LARGE company of homeless boys and girls left the, office of the, Children's Aid Society, a few days wince, in charge of one of the Western agents, to be provided with home.s and employment in the States of Illinois and Wisconsin, The number of destitute and friendless children applying to this Society tor aid (lining the pu'-t few week A ha:, bu-ji xeeod- injjly large.

By reference to the engravings the structure of the tongue will be easily understood. It is composed of two pieces of timber, say, for a two-horse wagon, one inch by two and three eighths, tapering toward the point in the usual proportion. The two parts are joined together at the front end, but separate back toward the bolster, and are laterally braced by metallic plates having studs at the ends which pass through the timber bars and are firmlyrireted. The ends of the bars where they meet the hounds are plated with metal, but are not attached in the usual manner. Before we state the method of attaching the tongue we must, however, describe the modification made in the general framework attached to the axle and sand bar. A straight bar of wood is placed be-tweim the hounds, running back through a recess in the top of the axle and bolted not only to it but to the center of the curved oscillating bar in the rear of the axle To the straight bar thus inserted, the reach or coupling bar is attached in tho rear of the front axle, thus allowing more cramping of the forward wheels without jamming them into the wagon box. By this means, also, tho draft is transferred to the reach without the intervention of the axle and the old-style king bolt, and all rocking motion of the axle is avoided. Instead of the king bolt running down through bolster, axle-tree, and reach, as commonly used, a fixed bolt rises from the axle upon which the bolster turns, tapering toward the top to allow some play. The two parts of the tongue are connected to the hounds by a suitable bolt, both the hounds and the straight draft bar above described being recessed to admit the ends of the tongue bars. The advantages secured by these changes are greater strength, grace, and lightness of parts, greater freedom in cramping, less wear in use, and consequent greater durability. The inventor, a practical wagon builder, informs us that wagons built with this form of front gear, have so completely superseded the old style, in the section where he resides, that he is now building none but the new style.

Nutmegs and Cloves The nutmeg-tree throughout the Indian Archipelago becomes fruitful at the age of seven years, and increases its produce till the fifteenth year, when it reaches the hight of productiveness. It is said to continue prolific for a quarter of a century in the Moluccas. Seven months in general elapse from the appearance of the blossom and the ripening of the fruit. The average produce of a tree from its fifteenth year may be calculated at five pounds of nutmegs, and a pound and a quarter of mace. The great harvest is in the months of September, October, November, and December, and there is a small one in May and June. The fruit having ripened, the outer integument bursts spontaneously, and is gathered by means of a hook attached to a long stick, and the mace, having been cautiously stripped off and flattened by the hands in single layers, is placed on mats for three or four days in the sun to dry. In damp and rainy weather the mace is dried by the heat of a charcoal fire, so as not to smoke it or blacken its surface. The mace liberated from the macy envelope is transported to the drying-house, and deposited on an elevated stage, the heat of a smouldering fire beneath passing upwards with the smoke between the rafters. Dried up kernels, which figure as damaged at public sales, have undergone too high a degree of heat in this process. The fire lighted in the evening is extinguished in the morning, the process of smoking is repeated for two or threemonths, when the nuts will be found to rattle freely. They are now re-garbled, and finally packed for transportation in tight casks, the insides of which have bsen smoked, cleaned, and covered with a fresh coating of water and lime. Cloves, which are planted in rich, red mold, yield generally at the end of six years, and reach the highest state of bearing at twelve years, when their average product is six to seven pounds of marketable fruit.' The fruit is terminal, and, when of a reddish hue, is plucked by the hand, so that the process of gathering it is tedious. It is then dried for several days on mats in the sun until it breaks easily between the fingers and assumes a dark brown color. It loses about 60 per cent in drying. When past its prime the love tree has a ragged and uncombed ap- pearance, and its existence is limited to twenty years, unless in very superior soil.—Grocer. How an Elevator Operates. When the boat containing the grain to be taken into store is moored alongside the pier, the " transferer" is swung out from the side of the elevator into the hold of the boat, and sinks into the loose cargo. This " transferer" is simply a series of metal scoops or buckets, fastened to a band inclosed in a siphon-shaped box, and when in operation these scoops run quickly through the grain, and carry it to an upper floor in the elevator, each one emptying itself as it runs over the crescent at the top of the siphon, and, going down the other leg of it, is ready for another plunge through the grain in the hold of the vessel. Arrived at tho upper floor, the grain is first weighed, a largo stationary hopper seated on a standing scale being provided, into which the buckets empty their contents ; and when the " beam" of this scale goes up it indicates that the number of bushels at which the scale has been set is in the hopper, when, by pulling one slide and closing another, the contents of the hopper are let out and the entrance of any further grain prohibited until it all escapes. In measuring or weighing a cargo by this means, the rule is to allow to the bushel sixty pounds of wheat, fifty-six of corn, fifty-six of rye, thirty-two of oats, forty-eight of barley, and sixty of peas. When weighed the grain falls on a sifter underneath the hopper, which is continually jogging backward and forward, where , in passing through the perforations in the iron bottom, i is cleansed of dirt, husks, pieces of cob, or such foreign matter, larger than the kernel itself, as may have got into the grain. It is thence conveyed again to a story above that on which the hopper is situated, to a screen containing still smaller perforations than those in the sifter, where it undergoes a second cleansing process, and from this point to a " blower," through which a blast of air is continually passing, and by this means it is still further cleansed of the fine dust that has collected in it. After this it may be either run directly into tho ship which is to take it to a foreign port, or put in store. If stored, it is transferred to its appointed bin, on any floor of the warehouse, by means of an auger-like apparatus inclosed in a square box-lika arrangement running longitudinally overthe roof of the warehouse. Thisis known as the " conveyer ;" and from it, at oblique angles, there run square tubes, which, when opened, let down the grain to any floor where it is desirable to store it. These tubes extending vertically through the entire depth of the building, and over the bin on each floor thereof have slides, which, on being drawn, allow the grain to make its exit into that particular compartment. Sometimes, in consequence of the fact that the grain lias become heated or sweaty, and is in danger of being totally spoiled, it is neceslary to put it through the drying process. In such event it is run into a large cylinder, through which hot air is continually pasped by moans of tubular pipes, and conveyed thence gradually into a bin in the coolest part of the warehouse. When it arrives here it is invariablydryand hard, having occupied about twenty or twenty five minutes in passing through the cylinder. Another operation is the " smutting" of the grain, or the taking from it the black fungus, which renders it diseased, and which, if allowed to remain in a cargo mixed with the sound grain, will in a short time spoil the whole of it.—New York Times. Water and Health. Let it be everywhere taught that water forms the largest component of the several textures and organs of both animals and vegetables ; it being in the proportion of more than three fourths of the entire body, and four fifths of the nutrient fluid, blood, consisting of it. Of the predominance of the aqueous overthe solid parts of the entire body, a striking proof is furnished in tho case mentioned by Blumenbach, of the dry mummy of an adult Guanche, which, with all the viscera entire, did not weigh more than seven pounds and a half. How large and constant must be the supply of water, in the first place, to meet all the wants of assimilation and nutrition, from the incipient stags of digestion to the final deposit from the blood in the cells, for the growth and support of the several organs; and, in the second place, to compensate for the continued loss of this aqueous fluid from the kidneys, and in the secretions from the skin and the gas-tro-intestinal and pulmonary mucous surfaces. In order to make up for the consumption and discharge ot water in these different processes of assimilation and of disassimilation or waste, the organism is supplied, first, by the fluid taken as drink ; secondly, by that which is absorbed by the skin and lungs from the surrounding air; and, thirdly, by the water largely contained in the substances used for food. Even of the solid food which we eat, not less than four fifths of it consist of water ; and we might go so far as to say that nine tenths of the wiiole of our food are little else than pure water. If loet in any great quantity from the body, there ensues an arrest of vital action, as may be easily seen in the lower animals. Lie-big shows how water contributes to the greater part of the transformations that take place in the living organism. Prout is decided in his appreciation of the dietetic value of water, and he ranks the aqueous, together with the saccharine, the oily, and albuminous, as the four great elementary, proximate, or primary staminal principles. We have well-authenticated cases of persons who have lived for a length of time while abstaining from all customary food, and whose only drink was water. Of this nature is the case of Reuben Kelsey, related by Dr. McNaughton, in the " Transactions of the Albany Institute," 1830. This man, aged 26 years, lived on water alone for fifty-three days. " For the first six weeks he walked out every day, and sometimes spent a greater part of the day in the woods. His walk was steady and firm, and his friends even remarked that his step has an unusual elasticity. He showed himself a week betoro his death, and was able to sit up in bed to the last day." Kelsey starved himself to death, under a delusion that when it waa the will of the Almighty that he should eat, he would be furnished with an appetite. Among the greatest names in medicine arc found the warmest eulogists oi water, as the most salutary and sustaining drink in health, and among the foremost remedies in disease. It is to be deeply deplored that the profession at large is not thoroughly imbued with this truth, and does not feel it to be a paramount duty to urge on all persons its importance, and an adoption of the practice flowing from it, as conducive alike to man's physical and moral well-being and pleasure. There is abundant testimony, derived from the personal experience and extensive observations of eminent medical men, to show that the inconveniences and dangers from living in hot climates are infinitely less for water-drinkers than for those who use intoxicating liquors of any description. A similar kindly and preservative power is displayed in favor of those who aro exposed to the extreme and continued cold of Arctic travel and navigation, and who, under circumstances, either from choice or necessity, have made water their sole drink, except when the occasional addition of tea or coffee was procured. This is the experience, also, of soldiers in the field, and ex-pososed to hardships of all kinds, and of men who have to carry on laborious occupations in a high temperature, as in iron founderies, glass-houses, etc.—By John Bell, M. D,, in Druggists Circular. A COEEBSPONDBNT proposeB the introduction to the Southern States of the date palm, the sugar palm, and the cocoa-nut palm—those palms furnishing fruit, sugar, oil, fiber, etc. He argues in favor of trying at least the experiment of intro-troducing these Indian palms ; and he holds that, if properly planted and cared for, they will flonripli find become profit. able to the South.
